Disclosed is a tool for turning a hex screw at the top of a denture compress containing denture flasks which comprises a hex key wrench having a shaft of finite length. Turning the hex screw in one direction causes pressure to be applied to a plate beneath it, and to the denture flasks within the compress. At one end of the shaft there is a handle perpendicular to the shaft, a T-handle. At the opposite end of the shaft a plurality of hex keys of different sizes are formed, in a contiguous relationship, the largest hex key being closest to the shaft and the smallest being furthest from the shaft. The T-handled hex key is supported by a frame which is attached to a flat base plate. The frame is perpendicular to the plane of the base plate, which has either within its surface or on its surface means for temporarily securing the dental compress thereto.
A denture compress tool for applying pressure to a compress containing denture flasks for making dentures, said tool comprising a substantially flat base plate having secured thereto a frame, said frame positioned substantially perpendicular to the top of said base plate, the frame comprising two opposing support members and a connecting third support member above the base plate, and a containment and a sleeve guide means having a cylindrical tubular structure at the mid-point of said frame, within which is positioned a cylindrical shaft, also positioned substantially perpendicularly to the base plate, and having at the top end thereof a T-lever for turning said shaft, wherein said lever and said shaft comprise a single contiguous, one piece member, having a plurality of contiguous hex keys of different sizes at the distal end of said shaft, and means contained within the base plate for temporarily holding a denture flask compress to keep it from turning while torque is applied to a hex screw at the top of said compress.
A modified Allen Wrench comprising a finite hexagonal shaft, said shaft having at both ends a first hex key of one cross-sectional size which is the shaft itself, and a second hex key contiguously attached to said first hex key having a cross sectional size different from that of said first key, about the same size thereof, and a third hex key of a smaller size than said second key and contiguous with the second key and further from the shaft.
